dns/dsc: Improve out-of-box behavior

(From the PR) The sample configuration refers to an invalid PID
file location, and a non-existent data directory.

 - Set PID file location to match RC script default
 - Create default data directory
 - While here, drop dependency on dns/dsp, which is not required
   to collect stats
